Hi @Hermit
In S32K3xx Reference Manual states that the "Random number generator (RNG) in this chip consists of a TRNG and a DRBG. Both are designed to be compliant to the highest strength in security as specified in BSI AIS20/31 and NIST SP800-90a,b,c".
Also, see the following thread, it has related information on the topic.
